Cost of Living Raise Calculator: Percentage Change in Salary
Work out the percentage of a cost-of-living raise between your old and new salary — and the annual dollar increase — so you can judge whether the adjustment actually keeps your pay in step with inflation.

How the numbers shift across typical situations for this calculator:
| Scenario | Raise | Annual increase |
|---|---|---|
| $60k to $61.8k (+3%) | 3.00% | 1,800 |
| $50k to $52.5k (+5%) | 5.00% | 2,500 |
| $80k to $81.6k (+2%, below inflation?) | 2.00% | 1,600 |
| $45k to $48.2k (+7.1%) | 7.11% | 3,200 |
How This Calculator Works
Enter your old salary and your new salary. The calculator finds the percentage raise and the annual dollar increase. Then compare the percentage to the inflation rate over the same period: a raise below inflation is effectively a pay cut in real terms.
The Formula
Percentage Change
Old is the starting value, New is the ending value
Worked Example
A raise from $60,000 to $61,800 is a 3% increase — $1,800 more a year. Whether that's a real raise depends entirely on inflation: if prices rose 3%, you've merely kept pace (a true cost-of-living adjustment), and if they rose more, your purchasing power actually fell. A cost-of-living adjustment (COLA) is meant to maintain buying power, not improve it — a genuine merit or promotion raise is the part above inflation.
Key Insight
The crucial distinction most people miss is between a cost-of-living adjustment and a real raise. A COLA keeps your purchasing power flat by matching inflation; only the portion above inflation is a real increase in what you can buy. So a '3% raise' in a year of 4% inflation is a 1% real pay cut, even though the number went up. Three takeaways: always compare your raise percentage to inflation over the same period to see the real change, recognize that years of below-inflation raises silently erode your standard of living, and use that framing in negotiations — asking for a raise that beats inflation is asking to actually get ahead, not just tread water. If your employer frames an inflation-matching bump as a generous raise, the real-terms math is your counter.
Frequently Asked Questions
How is the cost-of-living raise calculated?
Subtract the old salary from the new salary, divide by the old salary, and multiply by 100. From $60,000 to $61,800 is ($61,800 − $60,000) / $60,000 = 3%, a $1,800 annual increase.
What's the difference between a COLA and a real raise?
A cost-of-living adjustment (COLA) matches inflation to keep your purchasing power flat — it's not a real increase in what you can buy. Only the portion of a raise above the inflation rate is a real raise. A raise equal to inflation leaves you exactly where you were in real terms.
Did my raise keep up with inflation?
Compare your raise percentage to the inflation rate over the same period. If your raise was 3% and inflation was 3%, you broke even. If inflation was higher, your real (inflation-adjusted) pay fell despite the higher number — an effective pay cut.
Is a below-inflation raise a pay cut?
In real terms, yes. If prices rise faster than your salary, your money buys less than before even though the dollar figure increased. Several years of below-inflation raises compound into a meaningful erosion of your standard of living, which is why comparing to inflation matters.
How should I use this in negotiations?
Frame your ask around beating inflation. A raise that merely matches inflation keeps you flat, so to actually get ahead you need more. If an employer presents an inflation-level bump as generous, the real-terms math — that it's a 0% real raise — is your evidence to push for more.

Methodology & Review
The raise is the difference between the new and old salary divided by the old salary, multiplied by 100. It compares two salary figures directly; whether it preserves purchasing power depends on comparing it to the inflation rate over the same period.
